To all whom it may concern:

Be it known that l, WILLIAM F. CHAP- MAN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Method and Means for Preventing Skidding, of which the following is a specification.

This invention relates to means for and a method of preventing motor vehicles from skidding upon wet streets, and consists in the application of an anti-skidding material from a vehicle to the street directly in the path of the vehicle so that the tires come into contact with said material and are prevented from skidding.

An object of the invention is to provide a simple and reliable means to he carried by an automobile which may be operated at will to apply water soluble anti-skidding material to the street in the path of the wheels of the automobile.

A further object is to provide means of tht character described which will operate simultaneously with the application of the brakes of the vehicle to which it is attached.

Uther objects and advantages may appear from the subjoined detail description.

The accompanying drawings illustrate the invention:

' Figure l is a side elevation of an automobile showing it equipped with my invention; and a Fig. 2 is a diagrammatic view.

Referring to the drawings, 1 designates an automobile of the ordinary type, which includes front and rear wheels 2 and 3.

In carrying out my invention ll employ a. suitable receptacle 4; which is adapted to contain a quantity oil water soluble antiskidding material. llhis material may consist oat alum which is known to have anti skidding qualities and is water soluble.

Leading downwardly from the receptacle 4 is a pipe 5 having connection with a horiaontal discharge pipe 6. Depending fromv the ends of the discharge pipe 6 are vertical pi es 7 and 8, each of which provided with an enlarged flat mouth 9. These months 9 are curved in cross section and located in close ronimity to the tires 3 of. the automobile in spaced relation, hut close to the street. a

A valve 10 controlling the passage of material through the pipe 5 is carried by said pipe 5 and includes a lever 11 to one end of which is connected an operating rod 12. The valve is normally held in closed position .by a spring 13'which is connected with the pipe 5 and the lever 11.

A. bell crank 14 is pivoted upon the floor of the automobile and is connected with the rod 12. The bell crank 14 is provided with pedal 16 so that said pedal may he operated in the customary manner without opening the valve 10. To apply the material the extension 15 is moved so as to lie in operative relation to the pedal 16, that is, the

extension engages underneath the head of the edal. When the pedal is pushed downwar ly the bell crank 14 will be rocked,

causing a pull to he communicated to the lever ll through the rod 12, and the valve 10 to open. This will allow the material in'thereceptacle t to pass through the pipes 5, 6, l and 8 and be discharged through the mouths 9 upon the tires or the rear wheels 3 and upon the street in the path of the wheels 3.

The adhesive qualities of the material prevent skidding oi the automobile, and it has been found that alum and like materials prove highly satisfactory.

While l have shown and described means for applying the water soluble anti-skidding material to thetires of the rear wheels 3 Mill supply of anti-skidding material carried by the pedal member is operated and the antithe automobile, means to direct the material skidding material is applied. to the-street in the path of the wheels of Signed at Los Angeles, California, this the automobile, and means to control the 18th day of May, 1916.
